Potential sources of energy in Latvia

Solar Wind Hydro-power Biomass

Experts think that Latvian meteorological conditions - strong wind flows and storms; water resources have the capability for using alternative energy resources.

Not all local resources can be used. Parts of them are imported.

There aren’t enough experts to evaluate the current situation.

Energy suppliers need more support for this field. High production costs. All the territory isn’t suitable for alternative sources. There’s not enough space for plant cultivation. Damage for nature. Fish spawning, bird migration.

Passive use of solar energy. Solar collectors. Solar radiance for producing electricity. Sun energy. Solar ENERGY FOR HEATING.

In the future, Latvian

National Library is

going to set up the

solar electricity

panels on the roof.

Solar warming panels

are common on the

roofs of private

houses. For heating it’s

quite popular in Latvia.

Impact on the environment: We don't waste fuel, there is no air pollution and no noise.

Benefits: Production doesn’t depend upon the price of fuel or delivery; maintenance costs aren’t expensive.

It is a quick and simple way to get things done.

Adventages! No air pollution. No disposed resources. Less expenses for

petrol. New job opportunities. Highly efficient way of

electricity production. Fast and effective

projects.

Disadvantages! It disturbs migratory

birds. Technology is more

expensive than electricity production, using habitual fuel.

It is going to cause the price of electro – energy going up for the consumers.

There are an instability and volatility, so that's why wind energy can be used mainly as an additional source of energy.

There are 33 wind turbines with power 600kW.

It is The Biggest wind turbine park which is in operation in Baltics.

Average generator height is 77m.

The biggest windmill park in Baltics is in Grobiņa (southwest of

Latvia).

If you’d like to know,

where you can put

the wind turbines,

you can use the

wind map. There you

can see where the

winds are stronger

and where not. Data

was collected 10 m

high above the sea

level...http://www.windenergy.lv/karte.html

HPP in Pļaviņas. HPP in Ķegums. HPP in Rīga. HPP in Grūbe. And there are many, little hydropower

facilities, Micro hydroelectric plants in Latvia. Small hydropower facilities may involve a small dam, or be a diversion of the main stream, or be a run-of-the-river system.

Hydroelectric power is considered a renewable energy source. A renewable energy source is one that is not depleted (used up) in the production of energy. Through hydropower, the energy in falling water is converted into electricity.


The amount of electricity that can be generated by a hydropower plant depends on two factors:• flow rate - the quantity of water flowing in a given time; and• head - the height from which the water falls.The greater the flow and head, the more electricity produced.

How much electricity can be generated by a hydroelectric power plant?


Because the water cycle is continuous, hydropower is a renewable energy source.



In 1961, they started to construct the biggest power plant in Baltics and finished it in 1966.

10 hydro electro turbines, which produce 870MW electric energy.

It is the oldest hydro-electro plant on the river Daugava.

The third biggest in Latvia.

8 hydroelectric turbines, which produce 667 GWh electric energy.

http://www.lvportals.lv/likumi-prakse.php?id=229268

Six hydro power turbines with the total capacity of402MW.

In 2011 in Rīga HES produced 792,5 GWh electric energy.

This one is on the river Vaidava.

Remarkable with its 4,3m high, natural waterfall. The biggest of the kind in Latvia.

In Latvia biomass is derived from: Biodegradable waste, Crop residues, such as straw, Raps, Arisings from forestry and timber

processing, wooden chips, Fast growing willows.

Fossil fuel isn’t used. No pollution and no causes to

greenhouse effect. Costs are low. It reduces energy import. Sustainable development. Cheap fuel for the production of

electricity.


Dry, municipal dumping ground Getliņi in Rīga.

A plant for Municipal dumping ground in Liepāja is being planned.

The Rīga sewerage water sludge recaste system in Bolderāja.

Oilseed rape is the number one crop in fields of Latvia. Biogas can be produced from organic waste of oilseed rape.

Getliņi!Waste recycling

facility Uses high technology

which is safe for environment.

By recycling the waste, it can produce heat and electricity.
